Not too much in the immediate area, but there is plenty not too far away. To the north you have the Rocky Knob bike park in Boone, there is Kerr Scott in Wilkesboro.
You also have Kitsuma towards Old Fort and Black Mountain which you can add Toll Road and Heartbreak. Some other notables too. I'd brink the mountain bike,, lots of great riding in the area if you are willing to drive a little bit.
